Abstract: The goal of this research is to find the best dose of Oodev for enhancing female Betta channoides ex-situ reproductive performance. Four pairs of broodstock were acquired from a wild habitat in East Kalimantan, Indonesia, with total lengths of 4-5 cm and body weights of 0.6-0.9 g. The treatment was the delivery of Oodev maturation hormone to the broodstock by enrichment in Moina sp. as live feed at various doses, namely: without Oodev (control/T0), enriched with Oodev doses of 0.3 ml/l (T₁), 0.6 ml (T₂), and 0.9 ml (T₃). Inducing the Oodev hormone in B. channoides for 90 days of ex-situ maintenance using the oral method trough live feed enrichment was successful and consistently improved over the control. We evaluated utilizing 0.6 ml/L dose of Oodev as the applicate optimal dose with the highest total larvae generated and most frequent spawning (4 times in 90 days of rearing).
